Webb24 feb. 2024 · Amylose occupies about 20-25% concentration in starch, where the glucose molecules are condensed into long chains. The increased concentration of amylose in starch decreases the expansion potential and gel strength of the starch. Amylose is prevalent in plants as it is a constituent of starch molecules. WebbTable 1 shows the amylose and amylopectin content of granular (‘raw’) of white and yellow maize starch. Amylose is a long, mostly linear glucose polymer with a typical molecular weight of about 105–106 corresponding to degree of polymerization of 500–5000 (Takeda et al. , 1987). Normal maize starch is composed of 30% primarily linear
